SPECIFICATION forming part of Letters Patent No. 464,602 dated December 8, 1891.

Application filed June 2, 1891. Serial No. 394,867. No model.)

To r/JZ whom, it may concern:

Be it known that LCHARLIE LILLY DREW, a citizen of the United States, residing at Dubberly, in the parish of Webster and State of Louisiana, have invented certain new and useful Improvements in Combined Plow, Harrow, and Cultivator; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to combined agricultural implements.

The object of my invention is to provide by acombination of interchangeable parts an expanding harrow, a side harrow, a single plowstock, a double plow-stock, either right or left hand, a reversible cultivator, and a triple plow-stock or cultivator.

In the accompanying drawings, forming a part of this specification, Figure I is a side elevation of my single plow-stock, showing coupling-plates attached near the forward end of the beam. Fig. 2 is a plan view of the triple plow-stock. Fig. 3 is a plan view of a side harrow. Fig. 4 shows a plan view of an expanding harrow, and Fig. 5 is a detailed View of the side-harrow beam.

Referring more particularly to the drawings, A denotes the beam of the single plowstock, and A A the beams of the double plowstock. 7

B B B denote. standards, and 1) denotes bolts for securing the same to the beams.

b are braces riveted to the standards and detachably secured to the beams by bolts and nuts.

a denotes bolt holes passing vertically through the beams.

C denotes the handles pivoted to the forward part or forward of the center of the beam A, and C denotes adjustable braces or supports for said handles provided with holes 0.

D D denote coupling-plates secured to the forward end of the beam A by bolts (Z d, as shown in Fig. 1. Each of said plates are provided with slots or elongated bolt-holes. (1 cl denote bolts passing through said slots and through bolt-holes in the forward ends of the beams A A E E denote harrow-beams provided with teeth 6 e and having bolt-holes at both ends. e denotes a harrow-tooth detachably secured to the forward end of the beam A.

F F denote extensible or adjustable braceplates, having bolt-holesf. In Fig. 2 they are sho wn as crossing and secured together at the point of intersection by one bolt-IV.

G denotes a side-harrow beam, provided with teeth 9 and having a rectangular notch 9 cut obliquely across the top and provided with a bolt and nut.

H denotes a bent or curvilinear brace-rod, provided with a screw-threaded bolt and nut h at one end, the opposite end having a hook h formed therein. As shown in Fig. 3, said rod is hooked under the harrow-beam at the right-hand end around the barrow-tooth, and the opposite end is carried over on top of the beam A and bolted thereto.

Then the single plow-stock is used, the

coupling-plates D D may be removed by releasing the nuts and bolts.

To form a triple plow-stock or cultivator, place the brace-plates F F on the beam A crosswise, passing the bolt W through both plates at their point of intersection, as shown in Fig. 2. Then place the beams A A carrying the standards B B in position on either side of the beam A, and bolt the forward ends to the coupling-plates D D. The standards 13 B are then adjusted upon their beams backward or forward relatively to the center standard B to form either a right or left hand cultivator or triple plow-stock.

To change from a triple plow-stock or cultivator to a double plow-stock, remove the standard B and place the standards B or B back in position upon the beam until the bolt securing the standard brace can enter the rearmost bolthole in the beam.

.To convert the single plow-stock into a side harrow, remove the standard B and fit the notch g to the under side of the beam Aand secure the barrow-beam G thereto through the second bolt-hole from the rear in said beam A. Then hook the brace-rod H to the barrow-tooth at the right-hand end and secure the bolt h to the forward end of the beam A.

To convert the single plow-stock into an expanding barrow, place the coupling-plates l) D in position on the beam A. Then place the beams E E in position upon either side and secure said beam to the coupling-plates D D. Then boltthe rearends of the plates F F to the harrow-beams, and after adjusting said beams to form a harrow of the desired width bolt the plates F F by the bolt \V to the beam A, thus locking the said harrowbeams into the position adjusted. The harroW-tooth e is then placed in position on the beam A. It is evident that the elongated bolt-holes or slots in the eoupling-plates D D facilitate the ready adjustment of the double harrow beams. It is also evident that the plates F F serve as braces for the double and triple standard plow or eultivatorbeams and extensible-barrow beams, as well as means for adjusting the width of the expanding harrow. The holes a in the brace-plate 0 (shown in Fig. 1) serve for adjusting the handles to The holes fin the braces the height desired.

F F serve for adjusting the width of the expanding harrow.

llaving shown and described myinvention, what I claim, and desire to secure by Letters Patent, is

A combined agricultural implement having handles and a main beam common to the Various uses and fitted and adapted to the h
